What material is required for bridles, stage lines, and gantlines when performing burning, welding, and blowtorch operations?

The use of steel wire for bridles, stage lines, and gantlines during burning, welding, and blowtorch operations is crucial due to its high strength and durability, which are necessary to withstand the demanding conditions of these tasks. Steel wire has a high melting point and is less likely to be damaged or degraded by the intense heat generated during welding or similar activities. This ensures not only the safety of the operation but also the reliability of the equipment being used to support personnel and tools.

In contrast, materials like nylon rope or polyester webbing may be suitable for other uses but are not recommended in high-heat environments, as they can melt or lose strength under extreme temperatures. Manila hemp, while traditionally used in many marine applications for its strength, has limitations in its heat resistance and does not perform adequately in situations where cutting torches or welding equipment are used. Thus, steel wire stands out as the most appropriate material for these critical operations.
